Although not Oscar-worthy, Eminem's performance in this movie was absolutely brilliant, outshining seasoned actors like Kim Basinger and the recently Oscar nominated Michael O'Shannon.

QUALITY:
Good.  The transfer is ok.  It is a bit gritty and, although not intentional, it does add to the grittyness of the story a bit.

BONUS FEATURES:
Music Video, Making-Of

The bonus features are extremely weak (no music video for the Oscar winning "Lose Yourself?").  And, even though the grittyness adds tot he movie, I can't rightly chalk that up on the good side since the transfer is technically bad.  The movie is brilliant and the blu-ray is better quality than the DVD so it is worth the upgrade if you are a real fan of the movie.  Otherwise, don't bother.
